Request InfoEdmund OpticsBARRINGTON, N.J., June 3, 2008 -- Edmund Optics Inc. said its new in-line illumination telecentric lenses offer long working distances and a port for a fiber illuminator, providing tools for difficult machine-vision challenges that require accurate measurements of objects at varying distances, with limited room for imaging and lighting. Telecentric lenses offer accurate measurement because the apparent size of objects doesn't change with distance from the lens. Edmund Optics said its in-line illumination telecentric lenses overcome that limitation by incorporating a port for a quarter-inch fiber optic lightguide.
